[高考例题]
The Foreign Minister said, “______ our hope that the two sides will work towards peace.”
A. This B. There is C. That is D. It is
[答案] D
[解析] 本题考查it 作形式主语的用法，但B项却有很大的干扰性，但根据题干所提供的内容，B项很明显不符合逻辑。在中学教学中常与there be 结构连用的有：There is no doubt that … / There is possibility that … / There is no need to do sth. 等，这些句型在复习中要熟练掌握。
